In recent years, treatment using implants has become common. Since 2016, dental implants have been insured as part of strengthening health insurance coverage. Consequently, the demand for implants is increasing. Accordingly, the importance of implant maintenance has been emphasized. Of which, implant retrievability is an important factor in implant success. Although the screw-retained type is an advantageous easy-to-retrieve prosthesis, an occlusal point cannot make it to the central axis of the implant. Thus, we aimed to introduce an implant setting method (screw hole indexing) that enables the maintenance of the proper occlusal point and enables retrievability by marking the screw holes of the implant.

In livestock industry, there is growing interest in methods to increase the production efficiency of livestock to address food shortages, given the increasing global population.With the advancements in gene engineering technology, it is a valuable tool and has been intensively utilized in research specifically focused on human disease. In historically, this technology has been used with livestock to create human disease models or to produce recombinant proteins from their byproducts. However, in recent years, utilizing gene editing technology, cattle with identified genes related to productivity can be edited, thereby enhancing productivity in response to climate change or specific disease instead of producing recombinant proteins. Furthermore, with the advancement in the efficiency of gene editing, it has become possible to edit multiple genes simultaneously. This cattle breed improvement has been achieved by discovering the genes through the comprehensive analysis of the entire genome of cattle. The cattle industry has been able to address gene bottlenecks that were previously impossible through conventional breeding systems. This review concludes that gene editing is necessary to expand the cattle industry, improving productivity in the future. Additionally, the enhancement of cattle through gene editing is expected to contribute to addressing environmental challenges associated with the cattle industry. Further research and development in gene editing, coupled with genomic analysis technologies, will significantly contribute to solving issues that conventional breeding systems have not been able to address.

It is reported that the recurrence rate in intermittent exotropia is 20-50%. In this study, we evaluated whether the recurrence is reduced with asymmetric recession of bilateral lateral recti(LROU) in intermittent exotropia.Twenty-nine patients underwent the asymmetric LROU recession for intermittent exotropia with follow-up of 6-54 months. The amount of recession of lateral rectus muscle in deviating eye was 2mm more than in the fixating eye. Immediate postoperative overcorrection, the rate of orthophotia, and the occurrence of consecutive esotropia(ET) were analysed.The mean amount of immediate postoperative esodeviation was 16.5+/-7.4PD(0-34PD); four patients showed 0-4PD, 18 patients 11-20PD, and 7 patients showed considerable amount of ET as high as 21-30PD. Consecutive EToccurred in 6.8% of patients despite large amounts of postoeprative ET. The outcome of orthophoria was favorable, in 93.1% of patients in follow up of 6 months, 85.1% in 12 months and 78.5% in 24 months.This study suggests that asymmetric LROU recession is an effective procedure for the correction of intermittent exotropia.

To analyze a wide variety of polymorphisms in patients with endometriosis is important since this disease has a strong genetic component. Until now, more than 30 Korean studies have been performed in order to elucidate the possible role of specific polymorphisms in the susceptibility to endometriosis. The most meaningful polymorphisms in Korean patients with endometriosis came from studies investigating GSTM1, AhRR, ER-alpha, VEGF, AHSG, and TNF-alpha. However, following studies should be made to confirm the consistency of the data to have some implications in the prediction of endometriosis. In this review, we also present the future direction of the association studies in complex trait disease such as endometriosis.

PURPOSE: The purpose of this study was to examine the effects of workplace spirituality and organizational citizenship behavior on nurses' performance of nursing. METHODS: This study was done over a 6 month period, with 395 nurses participants from 5 different general hospitals with 400 beds in 4 regions of Korea. Data were gathered using self-reported questionnaires from July 23 to August 21, 2015. Data were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson correlation coefficients, and multiple regression analyses with IBM SPSS 21.0 program. RESULTS: Nursing performance showed positive correlations with workplace spirituality and organizational citizenship behavior. The significant predictors of the nursing performance by nurses were a master's degree or higher (β=.26), civic virtue (β=.19), courtesy (β=.12), 40 years of age or older (β=.09), a sense of empathy (β=.07), and a bachelor's degree in nursing (β=.06). These variables explained 39.2% of the variance in nursing performance by nurses. CONCLUSION: Based on the outcomes of this study, there is a need to develop intervention programs that can inspire nurse to show spontaneous organizational citizenship behavior, and enhance their workplace spirituality. Related variables including academic credentials should also be taken into account.

We report an autopsy case of secondary hemochromatosis associated with multiple frequent blood transfusion for the treatment of aplastic anemia. A 23-year-old man had been diagnosed as having aplastic anemia at the age of 13. He received a whole blood transfusion, about 1280 ml, every month during the past 10 years. Recently he developed diabetes mellitus and a congestive heart failure. The autopsy revealed that multiple organs were affected by secondary hemochromatosis, including the liver, heart, pancreas, spleen, bone marrow, stomach, thyroid gland, adrenal glands, and testes. The lungs and liver showed gross and microscopic findings consistent with a congestive heart failure in addition to hemochromatosis. The details are presented. This is a case of rare secondary hemochromatosis occurring in a young man and presenting the classic histopathologic changes indistinguishable from those of primary hemochromatosis.
